The staff was nice and helpful,talking English. Elevator was working. The room and bathroom size was ok. The bed was large (king size),but matress too tall. It was quiet. Clean. Had parking place at extra cost of 8 euro per day. It has a device that made cold air,like AC. I liked that there were nearby restaurants and even the hotel had a bar and terrace outside.

I didn't like that the pillows were very small,but we asked for additional. Also,that we were asked to move the car in the back parking,while in the morning we couldn't exit because it was tight and we scratched the car. From my point of view, the room also needs a closed closet (not just open shelves)and an insect net.

Cost effective, reasonably well kept hotel, on a quiet street, but walking distance from the city centre. Decent breakfast spread, though expensive at 15 euros. The rooms are simply decorated and furnished, and are overall pleasant.

The corridors smell of fried bacon each morning. This may be nice for some, but can be overwhelming for sensitive noses. The mattresses are soft and sink a little, so may not be best for folks with bad backs. There are some weird splashes/paint scrubs on some walls which could do with some cleanup.

The room is very cozy and clean. I slept incredibly well on their bed, good pillows. Room slightly warm but the fan worked good. Very satisfied with the breakfast, scrambled eggs were very well prepared, delicious chocolate cakes, fresh fruits, good tea options. I was very pleased with the breakfast quality and bed quality. The gym equipment is brand new, very good quality.

Just missing a fan or AC in the Gym room, but may come soon as the facility is new.

Breakfast was really nice, something warm, something cold, some fruits, coffee and tea - everything you need for a good start in the day. The rooms are comfortable, although the desk could be a little bit larger and the chair more ergonomic. Apart from that, everything on high standard - big, flat TV, high speed Internet, very clean.

small desk and chair which wasn't quite comfortable - could be more ergonomic, back is hurting after 30mins of sitting. ;)

A nice atmosphere, clean rooms, very good location and on a quiet street.

I was quite late for breakfast about 10:30 and they closing time is 11 o’clock. I was not yet finished and I was told to leave because they were closing, additionally there were no fruits left, no choice of breads, it was not what one would expect for a Sunday morning.

Very comfortable room with big living area, kind staff, very efficient service and quiet location.

The location was far away from downtown Cologne, but we knew that. It is fairly convenient to the train station. The hotel pricing in Cologne is a bit crazy, so we felt we paid more than it was worth, but it was the market rate at that millisecond of time.

The hotel is really one of the best of its kind. Amazing staff working 24/7, after an active day you can sit in a great lounge downstairs to enjoy a drink, the room was quite and really amazing in style and comfort, bed was very comfortable. Really great breakfast in Greek style - healthy and nutritious with lovely pancakes, feta cheese, salmon, olives, fresh juice and nice coffee - the best breakfast!! We didn't want to leave this place really.) Would come back to Leverkusen just for this hotel!))

All was amazing!

The room was not that big but comfortable, provided with all comforts. Breakfast was very good, the staff friendly and the location of the hotel also very good.

The Nikii is a very nice hotel, very clean and with very comfy beds. The personnel was very helpful and friendly. As a cyclist I really liked the breakfast with scrambled eggs but also with salads and yoghurts. Parking is available in the hotel garage for a fee of 8 euro.

I would have liked a water cooker in the room for making a coffee. Also, the area is not the most pretty in the world, being next to the Bayer plant. But for some that might just as well be perfect.

Very helpful staff and a comfortable room. There was an issue with our room that the staff were very quick to rectify. The staff were also helpful in telling us how to use the local trains. Room was comfortable but small. Perfect for just spending the night there. Parking was easy.
